08 May 2023 / 3 minutes to read

This section explains how to create a simple ButtonGroup, and configure its available functionalities by using the Essential JS 2 quickstart seed repository.

Dependencies

The following list of dependencies are required to use the ButtonGroup component in your application.

|-- @syncfusion/ej2-splitbuttons

Setup your development environment

To get started with the ButtonGroup component, you can clone the Essential JS 2 quickstart project and install the npm packages by using the following commands.

git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

The project is preconfigured with common settings (src/styles/styles.css, system.config.js) to start all the Essential JS 2 components.

Refer to the Button-Group component dependencies in system.config.js configuration file.

[src/system.config.js]

System.config({
paths: {
    'npm:': './node_modules/',
    'syncfusion:': 'npm:@syncfusion/'
},
map: {
    app: 'app',

    //Syncfusion packages mapping
    "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
    "@syncfusion/ej2-data": "syncfusion:ej2-data/dist/ej2-data.umd.min.js",
    "@syncfusion/ej2-inputs": "syncfusion:ej2-inputs/dist/ej2-inputs.umd.min.js",
    "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
    "@syncfusion/ej2-splitbuttons": "syncfusion:ej2-splitbuttons/dist/ej2-splitbuttons.umd.min.js",
    "@syncfusion/ej2-lists": "syncfusion:ej2-lists/dist/ej2-lists.umd.min.js",
    "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
    "@syncfusion/ej2-dropdowns": "syncfusion:ej2-dropdowns/dist/ej2-dropdowns.umd.min.js",
},
packages: {
    'app': { main: 'app', defaultExtension: 'js' }
}
});

System.import('app.ts').catch(console.error.bind(console)).then(function () {
document.getElementById('loader').style.display = "none";
document.getElementById('container').style.visibility = "visible";
});

The ButtonGroup CSS files are available in the ej2-splitbuttons package folder. This can be referenced in your application by using the following code.

[src/styles/styles.css]

@import '../../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';

Add ButtonGroup to the project

Add the HTML div tag with class name as e-btn-group and the button elements that should group inside the div element with class name as e-btn to your index.html file.

[src/index.html]

Orientation

ButtonGroup can be arranged in a vertical and horizontal orientation. By default, it is horizontally aligned.

Vertical Orientation

ButtonGroup can be aligned vertically by using the built-in CSS class e-vertical to the target element.

The following example illustrates how to achieve vertical orientation in ButtonGroup.
